Carbon dioxide concentrations in the atmosphere have crossed a major threshold: 400 parts per million. Here are five key points on how carbon dioxide is affecting Earth’s atmosphere and the role we're playing in it.
Broadcast meteorologists are a leading source of information about the atmosphere for the public, but many avoid mentioning global warming. New research finds barriers that may keep them from addressing the science of climate change on the air.
More than two days ahead of landfall, it was clear that Hurricane Sandy could bring higher water than New York and New Jersey had seen in decades. But for thousands of people in the area, the threat simply didn’t register. (Part 1 of 2)
The United States faces more varied weather risks than most nations on Earth, but we also have uniquely strong capabilities to confront these risks, thanks to decades of research conducted by government agencies, universities, and the private weather industry.
With its enormous computing capacity and speed, the new NCAR-Wyoming supercomputer will dramatically advance our understanding of Earth, helping to tackle major questions affecting our economy, health, and well-being.
Researchers at NCAR are working with forecasters and emergency managers to unravel the communication challenges around hurricanes like Isaac, which had relatively weak winds but a strong storm surge.
Studies show 63% of hurricane-related deaths occur inland. To help emergency managers prepare, NCAR scientists are pinpointing vulnerable populations using tropical storm winds, census data, and flood maps.
Until supplies approach a trickle—or a torrent—public attention seldom focuses on water issues. But water is consistently Topic A for a wide-ranging group of researchers.
States are having to make tough decisions regarding their water use and their interaction with water. NCAR scientists are involved in collaborative projects in Colorado, Louisiana, and Oklahoma to evaluate the long-term effects of today’s decisions.
As rising temperatures melt glaciers around the world, scientists are tracking the changes and helping glacier-dependent regions adapt to a changing water supply.
An engineer and water policy expert, David Behar is one of the nation’s leading voices on ways to weave weather and climate knowledge into water management.
The atmosphere has dealt Houston more than a few wild cards over the last few years, including two devastating tropical cyclones and unprecedented drought. While dealing with such weather threats, the nation's fourth largest city is also taking steps to tackle longer-term climate change.
Many facets of everyday life, from boarding a plane to turning on the lights or driving down the highway, are becoming safer and more cost-effective with the help of technologies rooted in atmospheric science.
Days lengthen as spring arrives, but several other signs of the season are showing up earlier and earlier. Some animals and insects aren’t adapting fast enough to this "asynchrony," and there's an increasing disconnect with legal dates that govern hunting and other resource management.
When weather disasters happen, is climate change to blame? The stories, video, and interactives in "Weather on Steroids" explore that question from a number of angles. It turns out that blaming climate change for wild weather's not that simple. Here’s why.
There's insurance, and then there's reinsurance - and both are affected by weather and climate. So how are insurers planning for a future where the impact of weather catastrophes meets climate change?
Experts from a variety of disciplines are joining forces to improve how severe-weather warnings are crafted and communicated. The "Weather-Ready Nation" initiative comes on the heels of a year packed with U.S. weather disasters.
According to Rick Anthes, the human and economic costs of weather-related disasters would be far greater without NOAA’s satellite and radar observations and weather forecast models.
